Hi,

I am getting the following error while building apache 2059. Please suggest.

I would suggest you to run full check on file /usr/lib/libexpat.so. Lots of command can be used for such task, here's some:::
- file: to check file type
- rpm -Va: to check file integrity
- ldd: check library dependancy

Hope it helps.

Hi,
The output for the first command looks weird. Check integrity of the file using rpm -Vv, OR if you had other server with same 'expat' version, compare its md5 signature (hint: md5sum command).

the result should look something like example below. first column should only contains dots.
$ rpm -Vv expat
........ /usr/bin/xmlwf
........ /usr/lib/libexpat.so.0
........ /usr/lib/libexpat.so.0.5.0
........ /usr/share/doc/expat-1.95.7
........ d /usr/share/doc/expat-1.95.7/COPYING
........ d /usr/share/doc/expat-1.95.7/README
........ d /usr/share/man/man1/xmlwf.1.gz
$

hope it helps.

Hi,

I donwloaded the latest diff patch from bugzilla. However it seems to give error while applying the patch.

$ patch patching file apu-conf.m4
Hunk #1 FAILED at 46.
Hunk #2 succeeded at 107 with fuzz 2 (offset -17 lines).
1 out of 2 hunks FAILED -- saving rejects to file apu-conf.m4.rej

Please suggest.
